why do we need to save the amazon rainforest

The importance of the Amazon rainforest for local and global climate Tropical forests and woodlands (e. g. savannas) exchange vast amounts of water and energy with the atmosphere and are thought to be important in controlling local and regional climates. Water released by plants into the atmosphere through (evaporation and plant transpiration) and to the ocean by the rivers, influences world climate and the circulation of. This works as a feedback mechanism, as the process also sustains the regional climate on which it depends. The Amazon rainforest could cure you What is the connection between the blue-green pills in your bathroom cupboard and the Amazon wildlife? The natural roots of medicine. For millennia, humans have used insects, plants and other organisms in the region for a variety of uses; and that includes agriculture, clothing and, of course, cures for diseases. Indigenous people such as the Yanomamo and other groups of mixed ancestry (e. g. the
mestizos of Peru or the caboclos of Brazil) have perfected the use of chemical compounds found in plants and animals.

Knowledge of using these plants is usually held by a medicine man ( shaman ), who passes on this tradition to an apprentice, a process which has been ongoing for centuries and that forms an integral part of peopleБs identity. With rainforests going fast, the continuity of this knowledge for the benefit of future generations is under threat. Untapped potential of the Amazon's plants Scientists believe that less than half of 1% of flowering plant species have been studied in detail for their medicinal potential. As the slowly shrinks in size, so does the richness of wildlife found in its forests, along with the potential use of plants and animals that remain undiscovered. Laurance, W. F. 1999.

More than half this forest lies in Brazil. The Amazon rainforest affords the planet with irreplaceable ecosystem services that are increasingly being recognized by researchers and policymakers. Precipitation Through transpiration, the Amazon rainforest is responsible for creating 50-75 percent of its own precipitation. But its impact extends well beyond the Amazon Basin, with Amazon rainfall and rivers feeding regions that generate 70 percent of South America's GDP. Models indicate that moisture from the Amazon influences rainfall as far away as the Western United States and Central America. Carbon storage The 390 billion trees across the Amazon rainforest locks up massive amounts of carbon in their leaves, branches, and trunks. A 2007 study published in Global Change Biology estimated the the forest stores some 86 billion tons of carbon or more than a third of all carbon stored by tropical forests worldwide.

Biodiversity The Amazon is home to more species of plants and animals than any other terrestrial ecosystem on the planet perhaps 30 percent of the world's species are found there. Besides their intrinsic value as living organisms, these species have potential value to humans in the form of medicine, food, and other products. Local benefits Within the Amazon Basin, tens of millions of people depend on services afforded by the forest. Rivers are the main vectors for transportation, while logging and collection of non-timber forest products are major industries in many cities, towns, and villages. The rainforest helps suppress but not completely eliminate the risk of fire, in addition to reducing air pollution. Fish in Amazon tributaries are a huge source of protein in the region. Annual floods replenish nutrients in floodplain areas used for agriculture. Amazon rainforest canopy
